information_schema refresh

I have 5.6.20 running in centos vm.

I tried to truncate a MyISAM table to reclaim space and checked the data_length column in information_schema.tables. In the session I have just truncated I can see that data_length is reduced. But in another session using mysql workbench the data length is still the old value. Value is not updated even after analyze.
Can you please let me know when will the information_schema values will be updated/refreshed across all sessions? I do not have access to db directory to see the table files.

Output in the session where truncate executed.

Table_name engine table_rows data_length index_length
contexts MyISAM 0 0 2048
events MyISAM 0 0 1024

output from workbench session
# table_name, engine, table_rows, data_length, index_length
contexts, MyISAM, 351521, 142650716, 37650432
events, MyISAM, 77317519, 3214007628, 1895477248
